Yes, silver does have the highest electrical conductivity of all metals. Moreover, it has the absolute conductivity to which other metals are compared. Currently, we have a scale of 1 to 100 to measure metals’ conductivity and silver is ranked the highest with the score of 100. The closest one to ever get to silver is copper with its conductivity of 97.

The second option is right as well. We all have jewelry and sometimes antique utensils made of silver.

Silver is also very malleable which allows us to create so many ornaments and jewelry from it. Though it is slightly harder than gold, it can be easily shaped in any design without crackling. The slight difference between silver and gold doesn’t influence the jewelry industry to the slightest. Moreover, silver pieces do not have a higher price due to its malleability.

So, the odd man out is option C. Silver is not a copper in nature. There is nickel silver that is an alloy; only in this case, we can consider it a somewhat truthful answer. The most widespread copper allow is brass. Bronze is an alloy consisting of copper (and the use of tin is quite common).

C is the correct answer. The silver is not an alloy of copper mixed with tin; it is free, it is a pure form of metal found in the crust of the Earth. Is, naturally, the alloy with other metals, such as gold, but in itself is not an alloy.
